973500172 Washer M4 Flat Small Ptn Iso 7 Suitable For Cutter Spare

1.The M4 specification precisely matches the M4 screws used in the cutting bed. With an inner diameter slightly larger than 4mm, it can tightly fit around the screw shank. The outer diameter is designed to be small, making it suitable for connection parts in the cutting bed with compact spaces, and avoiding interference with surrounding components due to an excessively large washer.

2.As a flat washer, its main function is to distribute pressure — when the screw is tightened, it can evenly transfer the pressure from the screw head to the surface of the connected part, preventing thin metal plates, plastic parts, etc. in the cutting bed from being deformed or damaged due to excessive local stress. At the same time, it can increase the contact area and reduce the risk of screw loosening, making it particularly suitable for connecting parts in the cutting bed that vibrate frequently.
